Good luck Kelly with the tests. Everything is going to be ok, just don't worry, you may even make it worse.
I had a big problem when I was in Romania (University). I went ot the ER in the middle of the night (on Friday) with 40C and they sent me back saying I have to continue taking the same pills my doctor prescribed on Friday noon for a week. Paracetamol and Aspirine!!!!! No tests, of course! And I had a severe urinary infection, almost died from it. First of all, they didn't want to come to the dormitory to take me with the emergency ambulance - they don't provide services to student dormitories!!! Lucky me, the university doctor came to see me once again first thing on Monday morning. She was so scared, she complained to the regional Chief doctor and the next time, after a month, with exactly the same problem, they not only took very good care of me, also gave me injections for 2 more weeks for free.
So, your dr is still good
